– If ‘Fade’ is selected, the output levels change gradually to the
new levels required over the time of one beat.
Example For two channels, #1 and #2, operating at 100% and 40%, which are
changed by a Sequence to levels 50% and 75% respectively, the
output levels of these channels would changes as follows:
If, however, the Sequence was in Fade mode, the output would
change as follows:
8.2.2 Sequences and Moving Lights
Whether a Sequence operates in Snap or Fade mode depends upon
the particular lighting requirements. However, Fade mode is
particularly relevant when controlling moving lights.
When a Sequence step occurs and the output levels change, the
moving lights change their position. A problem could occur when
moving lights are controlled on different channels by a Sequence,
and the change of the level on each channel is different.
Example If a Sequence operates in Step mode changing channel #1 from
100% to 50% (a 50% change) and channel #2 from 75% to 50% (a
25% change), then each light will move to the required position.
However, the time taken for each will be different as each channel
changes by a different amount, and it therefore takes a different time
for the each of the lights to move their positions.
To circumvent such problems, the Sequence should operate in
Fade mode. This ensures that the output levels change smoothly
over a time period, resulting in the position of the lights ending up
at the required positions at the same time, thus creating a more
fluid movement.
